Sea Change: Apple Guts Textbook Publishing

shutterstock_77959174The days of the $500 college textbook bills are, it seems, over. With Apple's announcement of iBooks 2, the world of textbooks is changed forever. Education is a hard nut to crack. There are bright spots and clever new ideas, but technology hasn't quite figured out how to do a better job than the "old ways." That's why Apple's decision to launch iBooks 2 and the attendant editing tools is so important: it tears down a number of entrenched technologies while maintaining the scaffolding of familiarity. It leaves the stuff that works and saves the schools, students, and parents money and time. In short, it stabs the publishing industry while it embraces it, ensuring that its old methods are no longer profitable but offering it new tools to go forward. Whether they survive the initial thrust, though, is anyone's guess.

Wall St Week Ahead: Strong start for stocks, but what's (Reuters)

NEW YORK (Reuters) ? Stocks rising, bulls rampant are motifs you might pick if designing a coat of arms for Wall Street at the moment. But the motto should read: Caveat emptor. Yes, buyer beware.

The S&P 500, a broad measure of the market valuation of the biggest U.S. publicly traded companies, is up 20 percent from its October closing low. It keeps climbing on a mixed bag of fourth-quarter earnings, improving U.S. economic data, and easing credit conditions in Europe. It now stands at its highest level since early last August.

We have already seen what is probably the first upgrade of a target level for the index this year courtesy of Credit Suisse.

The CBOE Volatility Index, or VIX (.VIX), a measure of what investors are paying to protect themselves against the risk of losses, is at its lowest level in seven months.

So it raises the question: Is this another Jackson Hole moment for risk assets?

At the Wyoming retreat in late August 2010, Federal Reserve Chairman Ben Bernanke sparked what was the second major leg of the stock market's rally from bear market lows the year before.

Is this the start of the third?

FRIENDLIER FOOTING FOR STOCKS

For Andrew Garthwaite, the Credit Suisse analyst behind the firm's more bullish stance, there are big changes afoot that are creating a more benign environment for stocks.

First, the European Central Bank's long-term repo operations are succeeding in reducing stresses in the region's banking sector. This week, three-month dollar Libor, the cost at which European banks can borrow dollars, marked its ninth straight day of declines.

Analysts say heavy cash infusions from the European Central Bank since late last year and signs of revived willingness to lend by U.S. investors in the new year show the banking system is flush with cash.

The U.S. economy is looking stronger than thought, with notable movement in the long-dormant housing market, where sales of previously owned homes just rose to an 11-month high.

In China, the engine of global growth whose manufacturing sector has been showing worrying signs of slowing, policymakers have demonstrated willingness to make conditions easier by lowering banks' reserve requirements.

"As we approach our year-end target two weeks into January, we have to ask ourselves the following questions: What has changed? Will equities rally further?," Garthwaite said in a research note.

His answer to the second question was yes. Credit Suisse raised its year-end S&P 500 target to 1,400 from 1,340. Critically, however, the firm did not overweight equities, saying the risks of a more severe recession in Europe and a slowdown stateside were still there.

HEALTHY DOSE OF SKEPTICISM

For Nicholas Colas, chief market strategist at the ConvergEx Group in New York, the rally remains largely untested. More scary headlines from Europe or any signs that the global economy is deteriorating could spark a sharp reversal.

Heading into the weekend, Greece was closing in on an initial deal with private bondholders that would prevent it from tumbling into a chaotic default. Creditors faced to 70 percent of the loans they have given to Athens.

"It's a confidence-based rally with the overhang of several still meaningful events to come," Colas said. "It is all well and good to say that the Greek default is well understood, but we haven't gone through it."

Outside the United States, there are mixed signals from the global economy, too.

China's factory activity likely fell for a third successive month in January. The HSBC flash manufacturing purchasing managers index (PMI), the earliest indicator of China's industrial activity, stood below 50.

The Baltic Exchange's main sea freight index (.BADI), which tracks rates to ship dry commodities and can be a useful gauge of economic activity, fell to its lowest level in three years on Friday on a growing surplus of vessels and a slump in cargo demand.

That is at odds with the work of RBC technical analyst Robert Sluymer. He sees growing outperformance of industrial metal copper to the safe-haven bet of gold as well as an upturn in a basket of Asian currencies as a bullish sign for the economy.

The caution generated by the mismatches in the various data points is perhaps reflected in by U.S. interest rates.

The yield on the U.S. 10-year Treasury note has hovered at 2 percent or just below for the last month despite a brief spike in mid-December. That suggests bondholders are not eagerly embracing the improving economy thesis for the moment.

"There is still a lot of skepticism about recovery, about moving into risk assets, about a lot of things," Colas said.

"If you really wanted to believe this about incrementally economic certainty and expansion ... I would have thought you'd expect to see the 10-year back over 2 percent."

EARNINGS, DATA AND THE FED

A blitz of earnings and economic indicators next week will provide an important gauge of the economy's health.

What's more, the Federal Reserve's policymakers will convene their first meeting of the year with a two-day session that starts on Tuesday. The Federal Open Market Committee, the Fed's rate-setting panel, will release its policy statement on Wednesday. No fireworks are expected, but a decision to release individual policymakers' interest-rate forecasts could alter expectations for rates on the margins.

Monday will start one of the two most hectic weeks of the earnings season. Marquee names due to report earnings on Monday include Texas Instruments Inc (TXN.O) and Halliburton Co (HAL.N), followed by Apple Inc (AAPL.O), DuPont (DD.N), Johnson & Johnson (JNJ.N), McDonald's Corp (MCD.N), Verizon Communications (VZ.N) and Yahoo! Inc (YHOO.O) - all on Tuesday.

Boeing (BA.N), ConocoPhillips (COP.N) and United Technologies (UTX.N) are set to release results on Wednesday. Thursday's earnings line-up includes 3M Co (MMM.N), AT&T Inc (T.N), Starbucks (SBUX.O) and Time Warner Cable Inc (TWC.N). On Friday, earnings are expected from Chevron Corp (CVX.N), Honeywell International (HON.N) and Procter & Gamble Co. (PG.N)

In the coming week, economic indicators to watch will include December pending home sales data, a key measure of the housing market, on Wednesday as well as the latest weekly claims for jobless benefits on Thursday. December durable goods orders and new home sales for December also will be released on Thursday.

The week will wrap up with the Commerce Department's first look at fourth-quarter U.S. gross domestic product and the final reading for January on consumer sentiment from Reuters and the University of Michigan.

In terms of companies beating expectations, fourth-quarter earnings season has not been as good as previous ones. Of the approximately 70 companies in the S&P 500 that have reported earnings so far, 60 percent have exceeded analysts' estimates, according to Thomson Reuters data.

In comparison, in the third quarter at this early point in the reporting cycle, 68 percent had beaten Wall Street's forecasts - well below the 78 percent in that category in the second quarter, Thomson Reuters data showed.

There have also been some high-profile misses on both revenue and earnings.

General Electric Co's (GE.N) fourth-quarter revenue fell short of Wall Street's expectations, with Europe's weakening economy and weak appliance sales the main culprits.

On the other hand, banks' earnings have served as a positive catalyst for the stock market so far. The sector has been one of the market's leaders despite mixed earnings, a sign that investors' worst fears did not materialize.

Fight Slippage with Friction

slippage friction bshSlip or grip?: What makes icy roads so slippery? Find out more about friction with this slick activity at home. Image: George Retseck

Key concepts
Physics
Friction
Mass
Gravity

Introduction
Have you ever driven up a mountain, seen a sign reading "Hazard! Icy Roads Ahead," and wondered why ice makes roads dangerous to drive on? The answer has to do with friction?specifically, the lack of it.

Specifically, in the case of driving a car down the road, the friction that allows the car to move occurs between the tires and the road. This friction normally allows the car to "grip" the road?keeping the tires in contact with the relatively rough road surface, and the driver of the car in control. However, when the road is icy, the friction between the two surfaces decreases, allowing the car to slip?rather than grip. You can replicate these situations much more safely at home using some common objects?regardless of the weather.

Background
Friction is the resistance to motion when two objects rub together. An example of low friction is when you sled down an icy hill. It's easy because both the sled and the ice on the hill are smooth and the surfaces of the sled's runners and the ice slide past one another with little resistance. On the other hand, sledding down a rough, concrete driveway is almost impossible due to the rough surface of the driveway, which provides resistance on the sled's runners. This is an example of high friction.

As you can imagine, friction happens when the rough parts of two objects catch one another as they rub together. The resistance that occurs depends on a value called the coefficient of friction. This is a measure of how much two objects interact with one another when rubbing together, and this depends on the materials that make up the two objects. The friction that takes place also depends on the mass of the moving object in the pull of gravity. All of these factors play a role in determining how much friction there is between two rubbing objects.

Materials
??? ?Two "two-by-four" or similar size wood planks, about one half meter long works best
??? ?Small plastic tub with lid
??? ?Sand or another dense material to fill the tub
??? ?Water
??? ?Freezer
??? ?Books
??? ?Ruler
??? ?Protractor
??? ?A carpeted area or a rug that can get damp (or a protective covering, such as a large plastic trash bag)

Preparation
??? ?Make sure that the pieces of wood have surfaces that are similar in roughness and are about the same length and width.
??? ?Take one piece of wood and soak it in water?this can be done by weighing the wood down in a bathtub filled with a few inches of water for at least 30 minutes.
??? ?Place the soaked piece of wood in the freezer overnight.
??? ?Fill the plastic tub with sand or another dense material and secure the lid.
??? ?Use caution (you may want to wear gloves) when handling the wood?especially if it is rough?to avoid getting splinters.

Procedure
??? ?On the carpeted area or a rug, build a ramp using several books and the dry piece of wood. Make sure the same part of the wood leans on the books for all of the trials.
??? ?Place the filled tub on the top of the ramp, with the edge of the tub lined up with the top end of the wood. Release the tub. If the tub slips down the ramp, remove the tub and lower the ramp height by removing a book. If the tub does not slip, remove the tub and raise the ramp height by adding a book. How high is the stack of books when the tub slips? What is the height of the shortest stack needed for the tub to slip?
??? ?Using the protractor, measure the angle where the ramp meets the carpet when the ramp is set up using the shortest stack of books needed for the tub to slip. What is the angle?
??? ?When you are done testing the dry piece of wood, retrieve the icy piece of wood from the freezer. (Because the icy piece of wood will thaw out over time, have everything in place and ready for testing it before you remove it.) How does the icy wood feel compared with the dry wood?
??? ?Using the icy piece of wood, test it on your ramp with the tub just as you did using the dry piece of wood. What is the height of shortest stack of books needed for the tub to slip on the icy piece of wood? Again, use the protractor to measure the angle of the ramp. What is the angle?
??? ?You can try testing each ramp with different book stack heights multiple times. Are your results consistent, or is there some variation?
??? ?Overall, which ramp?the one made with the icy or the dry wood?allowed the tub to slip at a smaller ramp angle?
??? ?Tip: If the icy wood thaws while you are testing it or seems dry, put it horizontally in the freezer and pour a little water all over the top of it. Leave it in the freezer for at least an hour. Test it again using the top side as the surface of your ramp.
??? ?Extra: How easily would the tub slip on a ramp made of other materials? Make a similar ramp using a plank covered with sandpaper, oil or aluminum foil. Alternatively, cover the bottom of the tub in these materials. How easily does the tub slip using the different materials?
??? ?Extra: If you know the ramp's height and length, you do not need a protractor to figure out its angle. All you need is to do some math: The equation used to solve the angle of the ramp is sin(theta) = opposite/hypotenuse. In the formula, "sin" stands for sine, "theta" is the angle, "opposite" is the ramp height and "hypotenuse" is the ramp length. Find out more about how to do this calculation at "Finding an Angle in a Right Angled Triangle" from Math is Fun Advanced. Does the calculated angle match the one you measured with your protractor?

'American Idol': 10 Predictions For Season 11

We gaze into the crystal ball to forecast the 11th season of 'Idol,' in Bigger Than the Sound.

Believe it or not, "American Idol" kicks off its 11th season Wednesday night (January 17), and for longtime fans of the show (like myself), it is a time of great trepidation. And not just because we've got nothing but auditions to look forward to for the next 354 weeks. Instead, rarely, if ever, has the future — nay, the very existence — of the program been as cloudy as it is right now.

I'm not about to float the notion that "Idol" may be on the chopping block; after all, it still pulls in massive ratings and is in about as much danger of being canceled as "CSI: Los Vegas" or whatever it's called. And it's already survived not only the exodus of Simon Cowell, but the addition (and subsequent subtraction) of several judges too. Rather, for the first time in its history, the show must not only compete with another budget-busting singing contest (that would be, of course, "The Voice," debuting after the Super Bowl next month), but it must redefine its relevancy. There was a time when "Idol" was capable of not only captivating the nation, but creating actual hitmakers, though, given the list of recent winners — Taylor Hicks, Kris Allen, Lee DeWyze — you probably wouldn't know it.

And while you could chalk that up to the whims (and demographics) of "Idol" viewers, the gender — and relative lack of success — of the show's past few champs does raise a rather interesting point: If anything, "American Idol" has become a show antithetical to the current state of popular music, which has become increasingly dominated by female artists like Adele, Katy Perry, Lady Gaga and Rihanna. Tellingly, it's debatable whether any of them could even win "Idol" these days; after all, the last female champion was Jordin Sparks back in 2007, and since then, we've only had two ladies even make the finale: Crystal Bowersox and Lauren Alaina, neither of whom fit the current pop-star mold. If anything, "American Idol" has become a boys club, and while that club has certainly turned up a few gems along the way (Adam Lambert, David Archuleta), it has also very much worked to the show's detriment.

Does that speak to an aging audience, the show's declining influence or both? Are the show's glory days behind it, or can it reinvent itself once again in 2012? Those are all weighty questions — ones that basically ensure I'll be glued to my set all season long ("American Idol" is nothing if not a rather fascinating social experiment, no?). Still, we're talking about a TV show here, so, in an attempt to provide some levity, here are my not-at-all serious predictions for the brand-new season. Accuracy not guaranteed, except for the Madonna one; I'm pretty sure she'll show up and call someone "reductive" at least once this year. So read on, fellow "Idol" aficionados," and hope my last prediction doesn't come true — even though I'm willing to bet it does.

» Early in the auditions, I shall pronounce a bluesy, female singer with a rough-and-tumble background the legitimate front-runner, at which point my wife will discourage me from drinking while watching "American Idol."

» Jennifer Lopez chokes a contestant after an ill-advised Marc Anthony cover.

» A disheveled Lee DeWyze, covered in blood of an indeterminate origin, will stumble onto the stage and attempt to play his post-"Idol" single, "Sweet Serendipity," only to break down in tears and repeatedly shout "You did this to me" until he is removed by security.

» In a shameless and ill-advised bit of integrated marketing, FremantleMedia teams with Lionsgate for a "Hunger Games"-themed episode, in which contestants, rather than being voted off, are shot through the heart with arrows.

» Madonna will periodically make guest appearances just to throw shade at everybody.

» In a stunning heel turn, Randy Jackson will lay out Ryan Seacrest with a vicious chair shot, pose over his fallen colleague, then remove his cardigan to reveal an "X Factor" T-shirt.

» Steven Tyler: Now with 70 percent more dangly accessories.

» In an attempt to spice up the show, "Idol" producers will force the top 12 to investigate paranormal activity at that haunted mansion from last season — you know, sort of like "Ghost Hunters" or whatever.

» Despite mounting evidence to the contrary, and based on nothing more than blind fandom, I will predict that this is the season where "Idol" rediscovers its old magic and produces a champion who ends up becoming a genuine pop superstar.

» A white guy will end up winning anyway.

One in five Americans mentally ill in past year (Reuters)

NEW YORK (Reuters) ? One in five adults in the United States, or nearly 50 million people, suffered mental illnesses in the past year with women and young adults suffering disproportionately, a government report released on Thursday found.

The survey by the Substance Abuse and Mental Health Services Administration found women were more likely than men (23 percent to 16.8 percent) to have experienced a mental illness, while the rate of mental illness among people aged 18 to 25 was twice that of those aged 50 and older.

The administration defined mental illness among adults as diagnosable mental, behavioral or emotional disorders, excluding developmental disorders and substance use.

The survey found that 5 percent of American adults, or 11.4 million people, had suffered a serious mental illness in the past year that substantially interfered with their lives.

According to the report, about 8.7 million American adults had serious thoughts of suicide in the past year, with 2.5 million making suicide plans and 1.1 million attempting to take their own lives.

Americans suffering mental illnesses were three times more likely to have developed substance dependence or substance abuse disorders than adults who had not experienced mental illness.

Among youths aged 12 to 17, 8 percent -- or 1.9 million teenagers -- experienced a major depressive episode in the past year, defined as a period of at least 2 weeks when a person experienced a depressed mood or loss of interest.

Those teenagers who experienced a depressive episode also had twice the rate of illicit drug use than teenagers who had not experienced depression.

The administration surveyed 67,500 people aged 12 and older in person around the United States.

The report is available here: http://1.usa.gov/zUrdpz.

Putin says he's ready for dialogue (AP)

MOSCOW ? Russian Prime Minister Vladimir Putin said Wednesday he is ready for dialogue with the country's newly energized opposition forces but doubts whether their leaders want to talk, according to Russian news reports.

Putin met with top editors of Russian news media and was asked if he is ready for dialogue in the wake of the massive protests that erupted over allegations of vote fraud in last month's parliamentary election.

Putin said some figures had been invited for talks "not long ago" but did not come.

"This question occurs to me ? what do they want? Do they want to show that there are no discussions or that they do not want to discuss," Putin was quoted as saying by the ITAR-Tass news agency.

"We're ready, and I am personally ready to meet with them, to talk. We invited them, but they did not come even one time," he said.

It was not clear from the reports specifically who had been invited or when the invitations were issued.

Putin, who was president in 2000-2008, now seeks to return to the Kremlin in an election on March 4. Although he is seen as almost certain to win, his image has taken a significant blow from the protests, including two rallies in Moscow that attracted tens of thousands of people in the largest public show of discontent in post-Soviet Russia.

Putin has belittled the protesters, dismissing them as Western stooges, and he has firmly rejected opposition demands that the parliamentary election be negated and a new one conducted.

In late December, he had appeared to effectively reject talks with the opposition, saying they had no common platform or leadership, so "who is there to talk to?"

Demi Lovato Supports Teens for Jeans [Video]


Did you know that there are over two million homeless teenagers in America? That's the bad news.

But here is some encouraging news: there's something you can do about it.

Demi Lovato is one of a number of celebrities (Kristen Bell, Julianne Hough) taking part in the Teen for Jeans campaign, which asks people to drop off used jeans at their local Aeropostale to be donated to shelters in your community.

In exchange, the school that donates the most pairs will receive $5,000 and Aeropostale pants for every single student! Seems like a no-brainer, doesn't it?
